To provide a vehicular front pillar structure capable of reducing air resistance during traveling of a vehicle, and improving snow clearing performance during snow falling, the appearance of the vehicle, and protection performance of a pedestrian at the time of contact with the pedestrian.

Ribs 40a and 42a arranged in a pillar outer cover 40 and a distribution path forming plate 42 project obliquely in the horizontal direction of a vehicle. Accordingly, when a shock force is applied to the pillar outer cover 40 from the front of the vehicle 1, resistance to the shock force from the front of the vehicle 1 is not applied to the front of the vehicle. Thus, the head damage value of a pedestrian at the time of contact with the pedestrian is reduced, and the protection performance of the vehicle 1 to the pedestrian is improved.
